I bought the deluxe range of covers in Jul2016 and both have now developed serious tears such that they are no longer fit for purpose. I noticed that some suppliers of garden covers offer a 5 year guarantee but when I enquired with GardenFurnitureCovers they stated that their guarantee is 12 months (this is the legal minimum for all products) and that their products will "deteriorate at different levels based on the UV exposure, the elements and how exposed the cover is". Uhm, well my covers are exposed to all weathers but I thought that was the purpose of a cover - to protect the furniture ? However, GardenFurnitureCovers have told me that they are happy that the goods (having protected my furniture for 18 months) have served me well and have invited me to purchase replacements (!) The covers fitted reasonably and appeared to protect the furniture for the time that they remained intact. In my view, despite the many longevity caveats expressed by the company's customer service staff (but not apparently mentioned on their web site) a life span of 18 months is not in my view satisfactory. Clearly it would not be sensible for me to take up the company's suggestion of purchasing replacements with a further 12 month guarantee since a number of competitors offer a 5 year guarantee on their products at much the same cost.
